1 UNITED STATES, P Ts roFFic-s Application filed April 27, 1931. Serial No. 533,078.

My invention has for its object to provide portion 12 of the closure plate 10, due to its an extremely simple and highly efficient venformation, reinforces said plate and gives tilator intended for general use but especial the same the necessary rigidity to keep its 1y well adapted to be embodied in the lower form. Preferably, as shown, the members of rail f a, i d w a h, the hinges 11 on the closure plate 10 are 53 To the above end, generally stated, the informed therewith and the other members of vention consists of the novel devices and comsaid hinges are directly secured by screws to binations of devices hereinafter described the rail 4. d d fi d i th lai A knob 13 by which the closure plate 10 Hi In the accompanying drawing, which illusmay be opened or closed is secured to said trates the invention, like characters indicate plate at the top and outer face ther ofi like parts throughout the several views. TO yieldingly hold the closure plate 10 R f i t th d i closed or in variable partially open positions Fig. 1 is a fragmentary outside elevation there is provided a frictional separable fasof the lower portion of a window sash havtoner comprising a spring clip 14c and a coing the invention embodied in the lower rail operating blade 15.
